Thread Ring Gauge Słowik M8×0.75 6G GO (pass) — metal thread inspection gauge

Słowik thread ring gauge M8×0.75 6G GO is a precision metal inspection gauge designed to check external metric threads with nominal diameter M8 and 0.75 mm pitch. Marked GO (pass), this gauge is manufactured to verify correct thread form and key dimensional features within the 6G tolerance class. It is intended for use in quality control of fasteners, turned parts and production inspections where reliable verification of external thread conformity to metric standards is required.

Advantages

The metal thread ring gauge provides a quick and repeatable means to confirm thread acceptability on finished parts. Built for durability and stable dimensional performance, it reduces subjective measurement and speeds up inspection processes. The GO marking ensures immediate identification of the pass gauge, helping to streamline workflow during assembly or batch inspection operations.

Suitable for

• Inspection of external metric threads M8×0.75 on fasteners and machine parts
• Production-line thread checks during machining or assembly
• Quality control in small-batch and serial manufacturing
• Verification of turned parts, studs and threaded shafts

Key specifications

• Thread profile: metric external thread
• Nominal size: M8
• Pitch: 0.75 mm
• Tolerance class: 6G (acceptance range for external threads)
• Type: GO (pass) ring gauge for verifying acceptable threads
• Material: metal gauge suitable for workshop use

How to use

Align the threaded part with the gauge and rotate the part or ring smoothly by hand to engage the threads. The correct external thread will screw into the GO ring without excessive force and without binding. Do not force the gauge onto a part; if the gauge does not turn freely, the thread should be rejected or measured further with calibrated metrology instruments. Keep the gauge clean and free of debris to ensure reliable results.

Usage recommendations

Store the gauge in a protective case or on a clean shelf to avoid nicks and wear. Periodically check calibration and inspect for damage; replace or re-certify the gauge if wear affects fit. Use together with additional inspection methods (e.g., optical or micrometer measurements) when tighter traceability or dimensional data are required.
